SCENARIO

You've joined RoyaltyHub, which administers music royalties. A contributor's share can differ by territory and change over time — somebody can be added after a release goes live, effective from a specific date. Royalties are reported monthly by territory and must use the agreement in force for each month.

your model must answer

01A contributor's total earnings from a given release in a specific month and territory?
02The applicable share for a contributor on a release in a territory for any historical month?
03By release and month, total royalties, breakdown by contributor, and the effect of any mid-period split changes?

This exercise’s brief could not be loaded.The guided questions and their model answers come from the review service. It looks like it is not reachable — start it with pnpm dev:api and reload.The canvas below still works, so you can model now and run the review once the service is up.
